| peridomestic distribution of triatoma garciabesi and triatoma guasayana in north-west argentina. | the reduviid bugs triatoma garciabesi carcavallo et al. (hemiptera: reduviidae: triatominae), previously known as t. sordida ståhl in the semi-arid chaco region, and t. guasayana wygodzinsky & abalos, vectors of trypanosoma cruzi chagas (kinetoplastida: trypanosomatidae), were found to occupy wide but different ranges of ecotopes in the peridomestic environment. at amamá and nearby rural villages in north-western argentina, a combined total of 1233 specimens were collected from 325/2314 (14%) si ... | 2000 | 11129702 |
| spatiotemporal patterns of reinfestation by triatoma guasayana (hemiptera: reduviidae) in a rural community of northwestern argentina. | triatoma guasayana (wygodzinsky & abalos) is a secondary vector of trypanosoma cruzi (chagas), the etiologic agent of chagas disease, in the chaco region of argentina, bolivia, and paraguay. the spatial distribution of t. guasayana in a rural community in northwestern argentina is described and analyzed using very high spatial resolution satellite imagery, geographic information systems, and spatial statistics. since a 1992 residual spraying with insecticides of all houses, site-specific domesti ... | 2005 | 16119545 |
| infestation of rural houses by triatoma infestans (hemiptera: reduviidae) in southern area of gran chaco in argentina. | the impact of control activities against triatoma infestans (klug) (hemiptera: reduviidae) in south america has a marked contrast within and outside the gran chaco region. development of a geographic information system, as part of an improvement in control program activities, allowed analysis of the spatial pattern of house infestations by t. infestans before and after house spraying with deltamethrin in the san martin department (an arid chaco region of central argentina). the overall peridomes ... | 2006 | 17017246 |
| first finding of melanic sylvatic triatoma infestans (hemiptera: reduviidae) colonies in the argentine chaco. | triatoma infestans (klug), the most important vector of chagas disease in southern south america, is a highly domiciliated species with well-known sylvatic foci only in the bolivian andean valleys and in the bolivian chaco, where melanic insects designated as "dark morphs" were found. after the tentative identification of two melanic bugs collected from parrot nests in a forest reserve in the argentine chaco as t. infestans, we conducted an intensive search there using mouse-baited sticky traps ... | 2009 | 19769054 |
| geometric morphometrics and ecological niche modelling for delimitation of near-sibling triatomine species. | identifying morphologically similar triatomine species is key to chagas' disease vector control and surveillance, but remains challenging when only qualitative phenotypic data are available. we investigated whether morphometric and ecological variation can provide additional criteria for species delimitation by combining geometric morphometrics and ecological niche modelling to characterize two near-sibling triatomine species, triatoma sordida and triatoma garciabesi (reduviidae: triatominae). w ... | 2010 | 21077924 |
